On the devbuzz website there is reference to 3.0 runtimes that can be installed on the 4.1 x scale PDA’s
Can this be done on the VGX system to run 3.0 apps?

Runtimes for what specifically?

Generally speaking libraries compiled for ARM for CE 3.0 will work on our CE 4.x devices but not in all cases.

Since you mention DevBuzz I'm assuming you mean the eVB 3.0 runtimes. If that's the case then it's important to know that eVB is not supported on CE 4.x by Microsoft, and therefore ADS doesn't support it on CE 4.x either. What that means is that nothing has been explicitly done to prevent eVB from working on CE.NET (I did some very basic functionality tests when 4.1 came out that worked) but if it doesn't there's no recourse.

The biggest issue that I can think that you'll hit is that most COM objects use ATL. CE 4.x uses ATLCE400.dll, but the CE 3.0 used ATLCE300.dll, so in order to register your COM objects you would have to copy ATLCE300.dll to the device along with the app and runtimes. Again, there's no guarantee that it will work even then.
